Primary property of a 2D project is given by geometric modelling done
in two dimensions only.
Only one planar slice is entered and the resulting two dimensional construction
calculated. There is no input regarding the third dimension - i.e. coordinates
of the axis perpendicular to project plane.

This project type is typically used to model a linear thermal heat bridge.

Final 2D Projekt contains ordered sequence of elements. The order of elements
is relevant, because later entered elements will
partly or fully overlap elements
earlier in the order if covering common plane area.

Primary property of a layered 3D project is given by its geometric
modelling of planar slices consecutive to each other (slices itself are identical
to a 2D project type).

This project type is typically used to model a point thermal heat bridge.

Three dimensional model is given by assigning a thickness to each
such planar slice.
In Antherm each such slice with assigned thickness is called leyer.

Final "layered 3D project" contains ordered series of
layers. The
sequence can be controlled by the
layers list.

Note: A three dimensional model will result in exactly same results as
its two dimensional counterpart only, and only if, the geometry and
conductivities do not change along one dimension and the extent in this
direction is exactly 1000 mm - i.e. 1,0 m.

Primary property of a 3D project is given by entering all three
coordinates in three dimensions directly. The resulting geometry of building
construction is described by series of cubes.

This project type is typically used to model a complex point thermal bridge.

The order of element cubes in the sequence is relevant, because later entered
elements will
partly or fully overlap elements
earlier in the order if covering common space area.

Note: A three dimensional model will result in exactly same results as
its two dimensional counterpart only, and only if, the geometry and
conductivities do not change along one dimension and the extent in this
direction is exactly 1000 mm - i.e. 1,0 m.

A 3D
project can be converted to a
2D project only if thicknesses (e.g. Z coordinates)
of all elements are equal. The resulting project will receive thickness of 1000mm (Z1=0,
Z2=1000).

A 3D
project can be converted to a
layered 3D project. The conversion will
create 3D Layers in the Z-directions for all Z-coordinates existent in the
project. Layer names will be derived from that Z-coordinate values. All
elements are then added accordingly to respective layers.Warning: This conversion need not be reversible.Important: Element of Z-thickness equal 0mm will
not be included in the conversion and ignored.
